H&K MP5SD6 HEAVILY UPGRADED/MP5 ACCESSORIES. In working condition just has a broken charging handle, other than that it works absolutely flawlessly, love this thing but i’m looking for an M4. i Invested a total of around $350 into this gun so i’m asking for $300 or best offer. i put custom picatinny rails on this gun myself, one of each side for lights/lasers, and one on the bottom for a foregrip Let me know if you would like the upgrades i put into this and more pictures of the gun/shooting videos. ACCESSORIES NOT INCLUDED (but can be included or sold completely separate from the gun if you would like)
